Mutations at the guanosine-binding site of the Tetrahymena ribozyme also affect site-specific hydrolysis.
Self-splicing group I introns use guanosine as a nucleophile to cleave the 5' splice site. The guanosine-binding site has been localized to the G264-C311 base pair of the Tetrahymena intron on the basis of analysis of mutations that change the specificity of the nucleophile from G (guanosine) to 2AP (2-aminopurine ribonucleoside) (F. Michel et al. (1989) Nature 342, 391-395). We studied the eff...
متن کاملSpecific Binding of a Dichloroacetamide Herbicide Safener in Maize at a Site That Also Binds Thiocarbamate
Dichloroacetamide safeners such as N,N-diallyl-2,2-dichloroacetamide and (R,S)-3-dichloroacetyl-2,2,5-trimethyl-l,3-oxazolidine protect maize (Zea mays) against injury from thiocarbamate and chloroacetanilide herbicides. Binding activity of tritium-labeled (R,S)-3-dichloroacetyl-2,2,5-trimethyl-l,3-oxazolidine (15 Ci/ mmol; referred to as [3H]Saf) was characterized in extracts of etiolated maiz...
متن کاملSite-specific mutations in the myosin binding sites of actin affect structural transitions that control myosin binding.
We have examined the effects of actin mutations on myosin binding, detected by cosedimentation, and actin structural dynamics, detected by spectroscopic probes. Specific mutations were chosen that have been shown to affect the functional interactions of actin and myosin, two mutations (4Ac and E99A/E100A) in the proposed region of weak binding to myosin and one mutation (I341A) in the proposed ...
